It’s generally said that the roots of radio
frequency identification technology can
be traced back to World War II. The Germans,
Japanese, Americans and British were all
using radar—which had been discovered in
1935 by Scottish physicist Sir Robert
Alexander Watson-Watt—to warn of
approaching planes while they were still miles
away. The problem was there was no way to
identify which planes belonged to the enemy
and which were a country’s own pilots
returning from a mission.
3. Under Watson-Watt, who headed a secret project, the British developed
the first active identify friend or foe (IFF) system. They put a transmitter
on each British plane. When it received signals from radar stations on the
ground, it began broadcasting a signal back that identified the aircraft.

Mario W. Cardullo claims to have received the first U.S. patent for an
active RFID tag with rewritable memory on January 23, 1973.
The U.S. government was also working on RFID systems. In the 1970s,
Los Alamos National Laboratory was asked by the Energy Department to
develop a system for tracking nuclear materials.
In the early 1990s, IBM engineers developed and patented an ultra-high
frequency (UHF) RFID system.
UHF RFID got a boost in 1999, when the Uniform Code Council, EAN
International, Procter & Gamble and Gillette put up funding to establish
the Auto-ID Center at the Massachusetts Institute of Technology.
Between 1999 and 2003, the Auto-ID Center gained the support of more
than 100 large end-user companies, plus the U.S. Department of Defense
and many key RFID vendors. It opened research labs in Australia, the
United Kingdom, Switzerland, Japan and China.

RFID stands for Radio Frequency
IDentifications
is an integral part of our life, which increases
productivity and convenience. It is the term
coined for short-range radio technology used
to communicate mainly digital information
between a stationary location and a movable
object or between movable objects.
RFID system consists of a tag; an antenna or
reader; a controller; and a database to store
information about tagged objects

RFID systems are composed of only three
basic components..
1. tag
2. an antenna or reader
3.a controller and a database to store
information about tagged objects
